Dear all
I just bought the LCD:
http://www.ebay.com/itm/180939111604?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
which has the LCD C2004A +PCF8574
with
PIN ASSIGNMENT / PIN SYMBOL FUNCTION
1 Vss Power Supply (0V)
2 Vdd Power Supply (+5V)
3 Vo Contrast Adjust
4 RS Data/Instruction Register Select
5 R/W Read/Write
6 E Enable Signal
7~14 DBO~DB7 Data bus Line
15 A Power Supply for LED BL (+)
16 K Power Supply for LED BL (-)
I disconnected the PCF 8574 from the LCD board and works fine with 4pin mode.
I cant operate it with the I2C and PCF8574.
As I can see in the lcd_i2c.lib we need pins E1 and E2 (?) as seen in the
AN #118 - I2C LCD and Keboard library example ( http://www.mcselec.com/index.php?option=com_content&task=view&id=82&Itemid=57)
since
P6 of PCF8574 is connected to LCD-E2
P7 of PCF8574 is connected to LCD-E1
But the LCD has only one Enable signal.
What is your suggestion? concerning the E,E1,E2 signals
